Abstract: 606,860. Gas-blast switches. NIJLAND, H. A. H. Jan. 21, 1946, No. 2009. Convention date, Feb. 19, 1942. [Class 38 (v)] A contact 3 of a pneumatically-actuated, gasblast circuit-breaker, is movable by a spring- returned piston 20 to provide an arc-extinguishing gap, and is connected with lost-motion to a rod 16 movable by an operating-mechanism (not shown) to provide an isolating-gap, and also to re-close the breaker. In Fig. 1, the contact 3 is joined by an insulator 14 to a rod 15, which is coupled to the rod 16 by a pin 17 and slot 18, and biassed therefrom by a spring 19. The contacts separate when the piston 20 slides into engagement with a shoulder 23 on the rod 15 and drives the latter upwards until arrested by an abutment 24. When the arc has been extinguished, the rod 16 is moved by its operating-mechanism to provide the isolating-gap, during which movement the gasblast is cut-off. The rods 16, 15, the insulator 14, and the contact 3 are together withdrawable through the end of the breaker. In Fig. 2, the piston 20 has a boss 23 closing the end 31 of the cylinder 21, whereby it is prevented from sliding on contact 3 until an adequate blastpressure is built up. When the full working- face of the piston is exposed, the piston snaps against the shoulder 23 and moves the contact 3 rapidly until arrested by the abutment 24.

Title: Improvements relating to activated phosphors
Inventor: VECHT ARON
IPC: C09K11/00
Filed: 1963-01-16
Abstract: Specification 1,008,651 describes a method of preparing a thin layer of an activated phosphor (photo - conductive, luminescent or electro-luminescent) on a foundation by condensing on to the foundation a thin layer, e.g. 0.1 micron thick, of the unactivated phosphor (a zinc or cadmium sulphide or selenide), coating this with a layer of flux-containing activated phosphor, and heating to activate the unactivated layer; in this Specification, the flux-containing activated phosphor is prepared by mixing the host material with an activator (e.g. copper nitrate), firing at 900 DEG C. and then quenching (e.g. in water or liquid nitrogen), grinding, and mixing with a flux (e.g. sodium chloride).  This results in a quenched supersaturated solution of activator in host, and when this is then heated adjacent the unactivated material, the activator readily transfers to this material; this heating may be at e.g. 450 DEG  C.

Title: Improvements relating to self-balancing electrical instruments
Inventor: PUCKNELL DOUGLAS ALBERT
IPC: G01R17/02
Filed: 1960-01-23
Abstract: 918,415. Electric selective signalling systems. FERRANTI Ltd. April 24, 1961 [Jan. 23, 1960], No. 2538/60. Class 40 (1). [Also in Group XXXVI] A voltage or impedance digitizing system in which an unknown voltage or impedance is repeatedly compared with a known voltage or impedance the known voltage or impedance being varied in such a way that it converges towards the unknown voltage or impedance is characterized in that in digitizing an unknown voltage or impedance of magnitude, say xyz, the known voltage or impedance is varied in the sequence 000, 900, 800, ... x00; x90, x80, ... xy0; zy9, xy8, . . . xyz. In the main embodiment, Fig. 1, an unknown resistance X, and a known resistance form two arms AD and BC respectively of a bridge. A constant voltage is applied across the diagonal AC of the bridge and the degree and sense of unbalance of the bridge is detected by alternately sampling the two ends of the other diagonal BD by a relay contact 21. A complete digitizing cycle comprises four sub-cycles, of ten clock-pulses each, one for each of the decimal denominations in the value of known resistance. In operation, a counter having four decimal denominations, T1, T2, T3, T4, is initially set to zero the state 0000. This counter, via the networks C1, C2, C3, C4, decides which known resistance is inserted in the bridge. Clock-pulses, from an oscillator 23 are fed via a divide-by-ten tube TA to a sub-cycle counting tube TB, and also to a gate 35 and to a relay 25 to control the sampling contact 21. When the sub-cycle counting tube TB reaches its No. 3 state, corresponding to the first sub-cycle, it opens a gate G1 leading to the highest denomination of the counter T1 ... T4. This permits a pulse from the No. 1 stage of tube TA to pass via a mixer U1 to set the counter in the state 9000. The counter then inserts a corresponding resistance into the bridge and if this is larger than the unknown resistance X then the pulses produced by the sampling contact 21 and amplifying and shaping circuits 34, U2 are in phase with the clock-pulses so that clock-pulses pass via the gate 35 and step the counter downwards from 9000 to 8000 to 7000 &c. until the known resistance is less than or equal to the unknown resistance X, whereupon the phase of the pulses produced by the sampling contacts 21 become out of phase with the clock pulses so that no further pulses pass the gate 35. A similar sequence takes place for the remaining subcycles. The sensitivity of the bridge can be varied by a switch 18. To digitize a voltage the arm CD of the bridge is opened and the unknown voltage is applied in place of the resistance X. A scheme is outlined whereby the sensitivity is varied automatically so as to give four significant digits.

Title: Improvements in or relating to egg products and processes for producing the same
IPC: A23L15/00
Filed: 1930-01-25
Abstract: In preserving egg white by drying, the liquid egg white is first allowed to ripen to a point at which it is substantially or slightly acid to phenol-pthalein but not acid to litmus.  If fermentable carbohydrate material such as cane sugar or dextrose be added before the ripening it may be allowed to proceed until the product is slightly acid to litmus.  The beating qualities of the dried product, when incorporated in an aqueous medium, and the flavour are improved. The drying arrests the ripening action.  In an example 10 lbs. of sugar are incorporated slowly into 1000 lbs. of egg white and the mixture is allowed to stand at ordinary temperature, the ripening taking place.  This normally takes 48-60 hours but can be hastened and a better product obtained by inoculating the whites with acid-producing micro-organisms.  By employing, for example, lactic acid bacilli which may be the kind used in ripening milk in the margarine and similar industries, the culture being prepared in the ordinary way, the ripening may be carried out in 24 hours or less, depending on the degree of inoculation.  Slow drying is employed and may be effected by spreading the material in thin layers on trays over which a current of warm air is passed.  The time taken is generally 26-30 hours and the air used may be heated to 40-45 DEG  C. Drying may also be carried out on drums in a more rapid manner, and the ripening of the product may consequently be carried on slightly further.  A concentrated liquid egg white may be obtained by incorporating the dried egg white with liquid egg white.  In an example, 13 lbs. of the dried white are slowly added to 100 lbs. of liquid egg white and the mixture allowed to stand for a day at about 40 DEG  F., after which it may be used or kept at about 0 DEG  F. until required.  The dried egg white added may contain modifying agents, e.g. water soluble polyhydroxy compounds such as cane sugar, dextrose or lactose, or small proportions of sodium chloride and like materials.  The polyhydroxy compounds may alternatively be added to the liquid white before or at the same time as the dried white is added.
